My invention relates to heating stoves of the type wherein the gases or products of com-r bustion may beL given a direct or indirect course to the exit flue; and it has for its principal object a device which will control both the direct and/indirect draft and which will prevent passage of the gases or products of combustion from the indirect flue through the exit flue whenthe device is in position to secure a direct 'draft through said exitr flue.

Other objects are simplicity and cheapness of construction and compactness of design.

The invention consists principally in a heating stove comprising a combustion chamcommunication with the combustion chamber of the stove. `The invention `also consists in the construction, combinations and arrangey ments of partsv hereinafter described and claimed.

Referring to the accompanying drawing,

my invention is shown in connection with a circulating heating stove comprising a base.. 1, an ash pit 2 supported thereon and provided with an opening 4 aifording access to` said ash pit, a tire pot 5 supported on said ash pit and provided at its bottom with a suitable dump grate 6,`- and a combustion chamber 7 located above said fire pot and provided with a substantially hemispherical top. The front wall of the combustion chamber is provided with the usual fuel receiving opening 8; and the rea-r, wall of said cham-L ber is providedfwith the usual smoke loutlet oreXit flue 9. The stovef'is enclosed withinl a suitable casing 10, whichis supported on the base 1 and is provided with a tire door 11 for.y closing the fuelreceiving opening 8 of the combustion `chamber 7 and anash door 12` for closing the 'opening in the `front of the ash c pit 2. The construction of heating stove thus far describediswell known and itis con-y sidered unnecessaryk i to illustrate rit in The rear portion of thedome of the combustion chamber lis provided with an indirect iiueor passageway `lwhose upperr end communicates with said chamber at thev top thereof and whose lowergend terminates` adjacent to the inner end of the exitor out# let flue 9 leading from the {rear wallof the combustion chamber. The end walls rofthe flue 13 extend downwardly on opposite sidesrr of `the exit or outletflue/Q. and are provided with pocketsor bearingsadapted to rotatably support v the horizontal trunnons 14 of a damper 714,k located opposite theinner end of the exit iiue 9 and used to control combustionby regulating the kdraft through the direct and indirect iiues 9 and 13, respectively.' One of ythe trunnions ofthe `damper projects through one side. of the stove and they enclosing casing therefor and is provided with a knob 15, whereby thefdamp'er may be manipulated. y The damper'lllis shaped and arranged so that when it is rotated yin a dif rection which ,will `cause the yupper portion tion' thereof to swingbackwards7 the upper edge of thel damper abuts against the yfront wall of the indirect flue 13 and thus estab-` lishes communication between ysaid iiue and combustion thus establishes direct communication be?y tween the combustion chamberand the exit flue while the upper portion of said damper swings rearwardly and thus closes communivcation between the indiiect Hue and the exit Hue.

By the arrangement described, the damperl may be manipulated so as to give the products of combustion a direct or circuitous kcourse to the exit Hue; It is noted as an important advantage of v my invention that when the damper yis manipulated to secure a direct draft for the products of combustion through` the exit Hue, communication between `the inverted Hue and the exit Hue is complet-ely cut v 0H, therebypreventing the passage of any of the products of combustion through said-indirectHue and thus causing a double draft which tends to check orfkill thedirect draft.

What I claim is:

f l. A heating stove comprising av'c'ombus tion chamber, an exit Hue leading horizontally vfrom said chamber adjacent tothe lower end thereof, a downwardly extending indirect Hue formed inthe wall of said chamber ber adiacent to said exit Hueand a damper niovably supported in chamber adgacent 'toy f Ui and communicating therewith adjacent tothe top thereof and adj aceut toi said exit Hue, andr a damper movably supported in said chamber opposite said exit Hue andadapted to said indirect Hue and! said exit Hue' when moved to a position to establish direc'tcom-y munication between said exit Hue andsaid chamber'. f e. v

2. A stove comprising a combustion chamber having a heating dome, an exit Hue com!y municating' with Ysaidchamber adjacent to lthe lower end thereof, an indirect Hue communi# eating at its upper end with the dome of said chamber and at its lower end'with said chamsaid exit Hue and to the lower end of said in-v direct Hue and adaptedto either admit the products of combustion'directly into said exit e Hue or to admitA 'them `into saidr exit Hue through said indirect'flue, said damper being shaped" and arranged to close communication Vbetweengthe adjacent ends of said indirect Hue and said' exit Hue when moved to a position' to establish direct communication' between said eXit Hue and'said chamber. y

3. A, heating stove comprising a combustion chamber having' a heating dome at the top thereof, an exit Hue communicating with said. v chamber below :said dome,l an indirect Hue formedin thefwa'll of said dome and coinmunicating at its Vupper end with the center of'said dome anda-t itsl lower end with said ycombustion chamber'adjacent to said eXitvl Hue, and ai damperfrotatably'supported lin said chamber oppositey said exit kHue and ,adaptedy in one position'of its lmovement to l establish communication between the indirectV Hue and the exitHue and toI closerdirect com munication between the combustion chamber and said exit Hue and adapted in the other position of its movementto establish direct communication between said combustion chamber and said exit Hue and to close communication between said indirect Hue and said enit Hue.

4. A heating stove comprising a combustion chamber having a substantially heinispherical dome at the top thereof, an exit Hue communicatingwith said chamber belowsaiddoine, an indirect Hue formed in t-he curved wall of said dome ,and communicating at its upper end with the interior of said dome adjacent to the center thereofan'd at its lower end with said chamber adjacent to the upper portion of said eXit Hue, the end walls of said indirect Hue extending downwardly on opposite side ofthe exit Hue, a damper rotatably supported in said chamber between the downwardly eX- teudingu walls of said indirect Hue opposite` said exit Hue and adapted to give the products of combustion a direct course from the chamber to the exit Hue or an indirect course from the dome of said chamber through said indirect Hue to said exit Hue, said damper being adapted to cut off communication between' said indirect Hue and said exit- Hue when moved to a position to establish direct communication between said enit Hue and said chamber.

5. A heating stove comprising a combustion chamber and a horizontal exit Hue leading from said chamber adjacent to the lower end thereof, a'downwardly extending indirectHue formed in the wall of said chamber and coinmunicating at itsupper end with the upper portion vof said chamber and communicating at its ylower end with said chamber at a point adjacent to saidv exit Hue, said indirect Hue having an inner lwall terminating at its lower endadjacent tothe upper portionfof said exit- Hue and having side walls extending downwardly on opposite sides thereof, and* a damper located opposite said exit Hue and mounted for vertical swinging movement towards and away therefrom .between the opposing dependingY end walls of said indirect Hue, said damper being adapt-ed in one position of its swinging movement to establish communication between the indirect Hue and th exitHue and to close direct communication between the combustion cham-ber and the ex t Hue, and beingadapted in the otherposi` tion of the swingingjmovement to'y establish direct communication between said combusytion chamber and said exit Hue and to closedirect communication between said indirect Hue and said exit Hue.
